I'm getting a new atv would like some advice on what machine to get. I have it down to 2. 2012 mud pro 700i for $8000 or 2011 4x4 550 efi with winch and plow included for $6600. Both are new will be used for trail riding flat land and plowing snow maybe pulling the kids around the yard on a sled. Any advice on what is the better value. I am a big guy 350 lbs...wondering if they will get the job done with me on it.
